Embodiment Construction

[0035] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to t...

Abstract

The invention relates to a blowing and sucking machine which comprises a main engine shell and a dust collecting bag, wherein a fan is arranged inside the main engine shell, and the dust collecting bag is connected to the main engine shell. An exhaust structure which enables the interior of the dust collecting bag to communicate with the exterior of the dust collecting bag is arranged on the bag wall of the dust collecting bag or inside the dust collecting bag. According to the blowing and sucking machine, the exhaust structure which enables the interior of the dust collecting bag to communicate with the exterior of the dust collecting bag is arranged on the bag wall of the dust collecting bag or inside the dust collecting bag, so that the pressure difference of the interior and the exterior of the dust collecting bag is decreased, and exhausting is facilitated.

Description

technical field [0001] The invention relates to the field of power tools, in particular to a blower and suction machine. Background technique [0002] Existing blower suction machine is in suction state, and suction pipe, volute, fan, dust collection bag jointly form an air duct circuit. In this air duct, there is no exhaust structure in the dust bag. The dust bag has two functions of dust collection and exhaust, but there is a mutual restriction relationship between dust collection and exhaust. [0003] If the dust collection effect is good, the air permeability of the dust bag should not be too good, because when the air permeability is too good, the relatively fine particles will be discharged, which will affect the dust collection effect; but the air permeability will cause the pressure inside the dust bag to be relatively high. High, the exhaust of the entire air duct circuit is not smooth, which in turn affects the efficiency of the suction state. If the exhaust effe...
